Stainless Steel Metal Expansion Joint DN900 DN1000

Best quality stainless steel metal bellows expansion joints

Metal bellows, also known as expansion joint, expansion joint, is mainly to ensure the safe operation of the pipeline. Metal bellows is a flexible thin-walled transverse bellows device with expansion function, which is composed of metal bellows and components. The principle of metal bellows is to use its elastic expansion function to compensate the axial displacement, angular displacement, lateral displacement and combined displacement caused by thermal deformation, mechanical deformation and various mechanical vibration. The metal bellows has the functions of pressure resistance, sealing, corrosion resistance, temperature resistance, impact resistance, vibration reduction and noise reduction. The metal bellows can reduce the deformation of the pipeline and improve the service life of the pipeline.

Performance of metal bellows

1. The metal bellows has good compensation

2. The metal bellows can withstand high temperature

3. Metal bellowss can reduce leakage

4. Vibration resistance and high-speed performance of metal bellows

5. The metal bellows can reduce the specific pressure of the spring

6. Possible torque transmission of metal bellows

7. The metal bellows can reduce the seal failure caused by scale through certain structural design
